In the tradition of Diddy, Mimi, and Chris Gaines, Beyonce Knowles would like you to take note of her new nom de stage: Sasha Fierce. The occasion: Beyonce’s new double album (coming November 18) is called I Am…Sasha Fierce. "I have someone else that takes over when it's time for me to work and when I'm on stage,” Beyonce explains, “this alter ego that I've created that kind of protects me and who I really am." Mmm, tell us about her. "Sasha Fierce is the fun, more sensual, more aggressive, more outspoken side and more glamorous side that comes out when I'm working and when I'm on the stage." You’ll be pleased to know that Sasha already has her own MySpace page.
